Kerri Walsh, volleyball

Why you should watch: Walsh is no stranger to gold medals. She and her teammate Misty May-Treanor, have taken the US volleyball team to gold twice, both in Athens and Beijing. We wouldn't expect any less this year.

Reed Kessler, equestrian

Why you should watch: Kessler is the youngest person to ever qualify for the US equestrian team. It should be fun to watch this young star compete since it is so rare for someone her age to qualify in this sport.

Lolo Jones, track and field

Age: 29

Why you should watch: Lolo Jones has one of the most inspiring stories out there. She grew up in a very poor household but was able to get a scholarship to LSU to run track. In the 2008 Olympics, Lolo tripped over a hurdle in the 100m, ruining her chance at a medal. This year is her time for gold.

Age: 23

Why you should watch: Maya Moore is one of the best female basketball players to ever play in college. She took UConn to back to back national championships while scoring an average of 20 points a game. We're sure nothing is going to slow her down at her first Olympics.
